The xtel is a brilliant pole upto 17 feet only.
As your in the pocess of going wfp, you may not have much cash to invest at 1st. But the pole is your primary tool and a good one will shave an hour off a 7 hour day.
Glass fibre poles are too bendy above 17 feet. If you can juggle things, invest in a good carbon fibre pole 1st and get the rest of your kit around it.
